DTC codes / U04xx · Invalid data received from a module / U0453
U0453 means the vehicle's main restraint control module has stopped receiving valid data from the left-side restraints control module, which is the satellite module responsible for left-side impact sensing and deployment. The computer detected missing, corrupted, or implausible messages on the dedicated communication bus that links the two modules.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
